Solution

Please find the answers below and explanations in parentheses:

1. Depolarizes (depolarization of membrane causes opening of sodium channels which causes outward flux of positively charged sodium ions into the matrix from the cells. This causes the matrix to be highly positive charged and the cell membrane becomes highly negatively charged)

2. Sodium ions, ECF (As the membrane depolarizes, the voltage gated sodium channels located over the plasma membrane open up and the outwards flux of sodium ion takes place leaving behind a large negative charge on plasma membrane)

3. Stimulated (the muscle cells contain afferent and efferent neurons which help in relay of information from muscles to brain and back to muscles. This flow of information takes place by the means of secretion of neurotransmitters from the brain in response to a stimulus)

4. Potassium ions, hyperpolarize (after the action potential has been performed, the sodium ion channels close to prevent further leakage of sodium ions in the ECF. However, the potassium channels remain opened for longer times and thus hyperpolarize the membrane with a net highly negative charge)

5. Resting membrane potential (this process is known as transmission of impulse in a cell by a cycle of polarization, depolarization and hyperpolazation)
